Bosch PEX 300 AE
Best OverallPros
- Excellent dust extraction via Bosch Microfilter system
- Low vibration for comfortable use
- Hook-and-loop pad is durable
Cons
- No speed control dial (variable trigger only)
- Pad can be tricky to change
The Bosch PEX 300 AE is a consistent top performer in the sub-£100 category. Owner reviews highlight its ability to produce a swirl-free finish even on softer woods, thanks to its 2.5mm orbit. The integrated dust collection is a standout feature, using a microfilter system that keeps the work area significantly cleaner than many rivals.
While it lacks a dedicated speed dial, the variable speed trigger provides adequate control. It is a well-balanced tool that feels solid in the hand. For DIYers and semi-pro users who prioritise a clean finish and dust management, this is the best all-rounder available.
Makita DBO180Z
Best Cordless (Body Only)Pros
- Great build quality from Makita
- Soft start motor reduces kickback
- Compatible with Makita 18V LXT batteries
Cons
- Battery and charger sold separately
- Lower max OPM than some corded rivals
The Makita DBO180Z is the go-to cordless option for users already invested in the Makita 18V LXT platform. It offers the freedom of cordless operation without sacrificing build quality. The soft start feature is a nice touch, preventing the sander from jerking when you pull the trigger.
Performance is solid for a cordless model, though its maximum 10,000 OPM is lower than some corded units. It is best for finishing work and light material removal. If you need maximum power for heavy stripping, a corded sander is still preferable.
DeWalt DWE6411
Best for Durability & PowerPros
- High max OPM for faster material removal
- Durable metal gearbox
- Comfortable rubber grip
Cons
- Dust box is small and fills quickly
- Vibration levels are higher than Bosch
The DeWalt DWE6411 is built for tougher jobs. Its 310W motor and high 14,000 OPM make it more aggressive than the Bosch, allowing for faster stock removal. The metal gearbox adds to its reputation for durability, making it a favourite for users who need a sander that can take a knock.
However, this power comes with a trade-off in vibration and dust management. The included dust box is small, so you will likely want to connect it to a shop vac. It is a solid choice for heavy-duty sanding tasks where speed is more important than a perfectly polished finish.
Ryobi R18ROS-0
Best Cordless ValuePros
- Excellent value for Ryobi ONE+ users
- High max OPM for a cordless model
- Includes a dust bag and vacuum adapter
Cons
- Build quality feels less premium than Makita
- Battery life can be limited on high speed
The Ryobi R18ROS-0 is the smart choice for anyone already using the Ryobi ONE+ battery system. It offers a high maximum speed of 14,000 OPM, matching the DeWalt for aggression. For the price of a body-only tool, it provides excellent performance for DIY tasks around the home.
It is not as refined as the Makita, and the plastic housing feels less robust. Battery life is adequate for small projects, but you may need a second battery for larger jobs. It is a fantastic value proposition for the budget-conscious DIYer.
Einhell TE-OS 2540
Best Budget / Occasional UsePros
- Very affordable price point
- High 400W motor for its class
- Includes a carrying case
Cons
- Higher vibration levels
- Dust collection is less effective
The Einhell TE-OS 2540 is the most affordable option on this list, making it ideal for the occasional user. It has a surprisingly powerful 400W motor and a variable speed dial, giving you good control. It comes in a plastic case, which adds to its value for storage.
However, the build quality and finish are not in the same league as the Bosch or DeWalt. Vibration is more noticeable, and the dust collection is basic. For a one-off furniture restoration or a few DIY projects, it is a perfectly capable tool that won't strain your budget.
What to check before buying a random orbital sander
Orbit Diameter: A 2.5mm orbit (like the Bosch) is best for a fine, swirl-free finish. A 2.0mm orbit is slightly more aggressive and better for material removal. For most DIY tasks, a 2.0mm to 2.5mm orbit is ideal.
Power (Watts): Corded sanders typically range from 250W to 400W. More power generally means faster material removal but can also mean more vibration. A 300W motor is a good balance for most users.
Speed (OPM): Variable speed is essential. Lower speeds (6,000 OPM) are for finishing, while higher speeds (12,000-14,000 OPM) are for stripping. A sander with a wide speed range is more versatile.
Dust Extraction: This is a critical feature. Look for a sander with a good dust bag or a port that connects to a vacuum cleaner. The Bosch PEX 300 AE is a leader in this area.
Corded vs. Cordless: Corded sanders offer unlimited runtime and consistent power. Cordless sanders offer convenience but require battery investment. If you already own batteries from Makita or Ryobi, a body-only sander is cost-effective.
Mistakes to avoid when buying a sander
Ignoring dust collection: Sanding creates a huge amount of fine dust. A sander with poor dust collection will make your workshop messy and can be a health hazard. Always prioritise models with good extraction systems.
Buying a sander with too large an orbit: A 5mm or 6mm orbit is for aggressive stock removal and will leave noticeable swirl marks. For finishing and general DIY, stick to a 2.0mm to 2.5mm orbit.
Choosing power over comfort: A high-power sander that vibrates excessively will be tiring to use and can lead to poor results. Look for models with rubber grips and low vibration ratings, especially for longer sessions.
Forgetting the pad size: The standard pad size is 125mm (5 inches). This is the most common size, so sanding discs are easy to find and cheap. Avoid less common sizes that limit your choice of abrasives.
FAQs
What is the best random orbital sander under £100?
The Bosch PEX 300 AE is widely considered the best overall due to its excellent dust extraction and smooth finish. It is the top pick for most DIYers.
Is a cordless random orbital sander as good as a corded one?
Cordless models offer convenience but are generally less powerful and have limited runtime. Corded sanders provide consistent power and are better for heavy or prolonged use.
What size sanding discs do I need for a 125mm sander?
A 125mm sander uses 125mm (5 inch) hook-and-loop sanding discs. These are the most common size and are widely available at hardware stores and online.
What does a 2.5mm orbit mean?
The orbit diameter is the size of the circular motion the sanding pad makes. A 2.5mm orbit is smaller and produces a finer finish, while a larger orbit removes material faster but can leave swirl marks.
Can I use a random orbital sander for polishing?
Yes, you can use a random orbital sander for polishing with the correct foam pads and polishing compounds. Ensure you use a low speed setting to avoid burning the surface.
How do I connect a sander to a vacuum cleaner?
Most sanders have a dust port on the back. You can connect a standard shop vac hose directly, or use an adapter to fit a domestic vacuum cleaner hose.
What is the difference between a random orbital sander and a palm sander?
A random orbital sander moves in a random pattern to prevent swirl marks. A palm sander vibrates in a fixed pattern and can leave visible marks on the wood.
Is the Makita DBO180Z a good sander for the price?
Yes, it is an excellent cordless sander for users already on the Makita 18V platform. Its build quality is superb, but remember you need to buy batteries separately.
Do I need a variable speed sander?
Yes, variable speed is highly recommended. It allows you to match the speed to the task, using slower speeds for finishing and faster speeds for material removal.
How long should a random orbital sander last?
With proper use and maintenance, a quality sander from Bosch, Makita, or DeWalt should last for many years of DIY use. Budget models may have a shorter lifespan.
Our verdict
For the best all-round performance, choose the Bosch PEX 300 AE for its superior dust extraction and finish. If you need a cordless model and have Makita batteries, the Makita DBO180Z is the premium choice. For the best value on a budget, the Ryobi R18ROS-0 is a great cordless option for Ryobi users.
